SOLE-EDGE-BURNlSHlNG MACHINE.

SPECIFICATION forming* part Of LettelS Patent N0. 246,622, dated September 6, 1881.

Application filed December 6, 1880. (No model.)

To all whom it may concern Be it known that I, JAMES W. MALOY, of Somerville, in the county of Middlesex and State of Massachusetts, have invented certain Improvements in Sole-Edge-Burnishiug Machines, ot' which the following is a specitication.

This invention relates to that class of soleedge setting or burnishing machines employing a reciprocating burnishing-tool, against which the edgeot" the sole to be burnished is pressed bythe operator, the reciprocating tool being guided in a curved path corresponding to the contours of a given portion of the sole-edge.

The invention has f'or its object, rst, to provide improved means for substituting one burnishing-tool for another while the machine is in operation and, secondly, to enable the cur nature ofthe path ofthe burnishing-tool to be readily changed from a concave to a convex curve, and vice versa.

The invention also has for its object to provide an improved rest or bearing for the bottom of the sole and for the operators hand while the sole-edge is being burnished.

To these ends my invention consists, rst,in theiinproved means employed for substituting one tool for another while the machine is in operation; secondly, in the improved means employed for changing the curvature of the path ofthe tool 5 and, thirdly,in theimproved rest, substantially as hereinafter specified, and particularly pointed out in the claims.

Oftheaccompanying drawingsforminga part of this specification, Figure l represents a side elevation and partial section of a machine enibodying my invention. Fig. 2 represents a front elevation ot the same. Fig. 3 represents a section on liue ze', Fig. l. Figs. 4 and 5represent sections on line a z', Fig. 1, the curved guide or holder being reversed in Fig. 5 from the position shown in Fig. 4. Fig. 6 represents a perspective view ot' the reciprocating curved block or carriage carrying the burnishing tool or tools; and Fig. 7 represents a sectional view of the burnisher-shaft, illustrating a mode of lubricating the same.

The same letters ot'. reference indicate the same parts in all the ligures.

In carrying out my invention I employ a curved frame or holder, F, as a guide for the block or carriage Gr, which is adapted to reciprocate in said holder.

H represents a cylindrical box, to which the holder F is rigidly attached. The box H is journaled in a box, H2, on a supporting-frame, I, and is adapted to rotate therein so as to pre` sent either sidevof the curved frame F at the front of the machine.

J represents a shat'tjournaled in the frame I, and extending through the box H into the .holder F, where it is providedwith au eccentric-pin, K, entering a box, L, adapted to slide in a transverse groove in the block orcarriage G. The shaft J is rotated by a belt, M, on a pulley, N, affixed to said shaft, and by its rotation reciprocates the block or carriage G (which is caused by the curved holder to move in a curved path) with a short stroke.

rlhe box H is provided with ahandle, O, projecting through a slot in the box H2, said handle enabling the operator to semi-rotate the box and its depending holder F, and thereby bring either side of the holder to the front, as shown iu Figs. 4 and 5, thus causingtheblock or carriage to move ina curve cont'orming either tothe convex edge ofthe sole or the concave edge of the shank.

The block or carriage G is provided by preference with two burnishing-tools, Q Q, one adapted to work on the sole-edge and theother on the shank-edge, said tools being attached to the block or carriage by forked arms R R on the tool-Shanks It R', passing through slots S S in the holder F.

It will be seen that the semi-rotation of the box H and holder F, above described, also reverses the positions of the tools Q Q, bringing one to the position previously occupied by the other, said rot-ation being easily e'ected while the machine is in operation.

In Figs. l and 2 I have shown a rest, T, for the face ot' the sole while the edge is being burnished. The rest is composed of a plate piv-` oted at its upper end to a shank, V, suitably attached to the frame I. The pivot of the rest is located as near the working-face of the buruishing-tool as possible, and the shankVis so formed that the back ofthe restis unobstructed, so that the operators fingers can be blaced thereon, as shown in dotted lines in Fig. 1. The pivoted rest enables the operator to turn the boot or shoe and rest together in presenting the toe portion of the sole to the tool, the pivot of the rest acting', as it were, as a pivot for the sole.

It will be seen that the employment of the pi voted rest enables the operator to perfectly control the sole while theJ toe portion is being burnished, the portion of the rest below the pivot constituting a lever for the operator to grasp while turning the sole. The rest receives an outward yielding pressure by means of a spring,V2, applied to the inner end of the shank V, which shank is adapted to slide into and out of a socket in the frame I.

In the construction shown in Fig. 7 the reciprocating block or carriage Gr is provided with a tool-holder, A2, projecting through a slot in the bottom ot' the guide or holder F. This arrangement brings the burnishingtool in line with the shaft J, so that the tool will he less liable to displacement or breakage than when the tool is offset from said shaft.

I prefer to provide the shaft J with an oilchannel, D2, extending from its upper end to the curved guide or holder F, so that. the latter may be lubricated through the shaft. The upper end of the oil-ehannel is enlarged so that it will contain a supply ot'oil,which passes to the upper bearing of the shaft through holes B2, filled with wicking. A valve, C2, is placed in the oil-channel to prevent more oil than is desired in the holder F from passing down the oil-channel. The lower bearing of the shaft J is lubricated through orifices F2, containing wicking, and communicating with the channel D2.

Heretol'ore burnishing-machines have been provided with a reversible tool-holder, whereby tools ot' different shape for operating upon different parts of the sole are held in a convenient manner -to be brought into position for use without stopping' the machinery.

I claim as my inventionl. The combination of a curved frame or holder, F, containing and guiding in a curved path a block or carriage, G, adapted to he reciprocated in said holder by means substatitially as described, one or more burnishingtools suitably connected to said carriage, and a tubular box supporting said holder and journaled in a supporting-frame, said box being adapted to semi-rotate in its supporting-frame, and thereby bring either the concave or con- Vex side of its curved holder to the front, as set forth.

2. The combination of a frame or holder, F, containing and guiding a block or carriage, G, two burnishing-tools, Q Q, connected, respectively, to opposite sides ofthe carriage, a tubular box, lvl, supporting said holder and journaled in a supportingframe, and means, substantially as described, for reciprocating the block or carriage in its holder, the box being adapted to semi-rotate in its supporting-frame, and thereby bring either burnishing-tool into operative position` as set f'orth.

3. In an edge settingor burnishing machine, a. rest or bearing, T, a shank, V, to which said rest is pivoted, and a spring, V2, for imparting a yielding character to said shank and rest, combined and arranged tooperate substantially as described. Y

In testimony wliereot'I have signed my name to this specificatioinin the presence oftwo subscribing witnesses, this d day of December, A. D. 1880.
